DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 416,056, dated November26, 1889.

Application filed June 5, 1889. `Serial No. 313,200. (No n10del.)

To @ZZ whom it 'Imag concern/.-

Be it known that we, FRANK V. GAY and ARTHUR A. VIXOM, citizens of theUnited States, residing at Clay Centre, in the county of Clay and Stateof Kansas, have invented a new and useful Door-Check, of which thefollowing is a specification.

This invention relates to door-checks; and it has for its object toprovide a device of this class which shall be simple in construction,eticient, and comparatively noiseless in operation, in which theretaining-springs may be adj usted at any desired angle, and in whichthe tension of the said retaining-springs may be conveniently regulated.

The invention consists in the improved construction, arrangement, andcombination of parts which will be hereinafter vfully described, andparticularly pointed out in the claims.

In the drawings hereto annexed, Figure l is a perspective view showingour improved door-check applied in position for operation. Fig. 2 is alongitudinal sectional view. Fig. 3 is a plan view. Fig. 4C is a bottomplan. Fig. 5 is a perspective view illustrating the parts constitutingour invention separated or detached from each other.

The same letters refer to the saine parts in all the gures.

A designates a shank or stein provided at its inner end with ascrew-threaded extension B, by means of which it may be attached to thewall or wash-board of a room in operative position, as shown in Fig. lof the drawings. Itdesircd, the screw-threaded extension might projectdownwardly to enable the device to be attached tothe vtloor of a roomwithout departing from the spirit of our invention. The outer end of theshank A is provided with an approximately circular horizontal plate C,to which a pair of leaf-springs D D are connected by means of a centralpivotal bolt E. The said leaf` springs, which are arranged,respectively, on the upper and under sides of the plate C, are providedat their outer ends with coils or rolls F F, facing each other, andadapted to clamp and hold the doorbutton between them, as will bepresently more fully described. The horizontal plate C is provided nearits inner end with a segmental slot G, which is concentric with thepivoting-bolt E. Through the said slot and through perforations Il inthe inner ends of the leaf-springs D extends a bolt I', which alsoserves to connect a pair of tensionsprings J J to the outer ends of theleafsprings D D. The said tension-springs are provided at their innerends with perfora- They also are provided with perforations L for thepassage of the pivotal bolt E, and be-.

tween the said perforations K and L they are provided with shoulders M.It will be seen that the leaf-springs D and tension-springs J maybeswung upon the pivotal bolt F. to any desired angle with relation to thestem or shank K, and they may be secured in any position to which theymay be adjusted by means of the bolt I, which works in the segmentalslot G. rlhe ends of the bolts E and I are provided with nuts,designated, respectively, by letters N and O. The said nuts are square,and their sides abut against each other so that the said nuts shall keepeach other locked. The heads of the bolts are provided with notches P toenable them to be adjusted by means of an ordinary screw-driver. It willbe seen that the pressure of the tension-springs J upon the leaf-springsor retaining-springs D D may be regulated by properly adjusting the boltE.

(.2 designates the door-button, which is composed of a screw-threadedshank R, having an integral head S, provided on its inner side with anannular flange XV, over' which the button T, which is made of hardrubber, is molded. It will be seen that by this construction the buttonis secured very rigidly to the screw-threaded stem, and is not liable tobecome detached when the said button in operation is disengaged from theretainingsprings. The button is constructed with a head T, which isrounded and adapted to enter between the coils or rolls F F at the outerends of the retaining-sprin gs, and shoulders U U, adapted to abutagainst the said coils or rolls.

The operation of the invention and its advantages will be readilyunderstood from the foregoing description taken in connection with thedrawings hereto annexed. The doorcheck and the button are attached insuitable IOO positions, respectively, to the wall of the room and to thedoor, and the retainin g-sprin gs are then adjusted at any suitableangle at which they will most readily be engaged by the doorbutton.l/Vhen the door is swung open, the head T of the button will enterbetween the outer ends of the retaining-springs, which Will clutch andhold the said head T and pre- Vent the door from being accidentallyshut. Vhen it is desired to shut the door, the head T of the button maybe disengaged from the retaining-springs by pullingthe door with therequisite degree of force. The tension of the retaining-springs may beregulated by loosening or tightening the bolt E, thus causing thetension-springs J J to bear upon the said retaining-springs with agreater or less degree of pressure.

The construction. of the device is simple and inexpensive, and it may bemanufactured at a small expense.

Having thus described our invention, what We claim, and desire to secureby Letters Patent, is-

l. In a door-check, the combination, Witha shank having arearwardly-extending screwthreaded extremity and a horizontalcentrallyperforated plate provided with a segmental slot in rear of andconcentric with said perforation, of the leaf-springs mounted pivotallyupon a bolt extending through the central perforation and having rollsor coils at their outer ends, the tension-springs secured by saidcentral pivotal bolt to the outer sides of the leaf-springs, connectedby a bolt extending through the leaf-springs and through thev segmentalslot and having shoulders formed intermediately between the said pivotaland connecting bolts, and the door-button formed with a head adapted toengage the rolls or coils at the outer ends of the leaf-springs,substantially as and for the purpose set forth.

2. In a door-check, the combination of a horizontal plate having asegmental slot, the retaining-springs connected pivotally to the upperand under sides of the said horizontal plate, the tension-springsmounted upon the pivotal bolt, the tightening-bolt extending through thesegmental slot and connecting the inner ends of the retaining-springsand the tension-springs, and the nuts having flat sides abutting againstand locking each other, substantially as and for the purpose setforth.

In testimony that We claim the foregoing as our own We have heretoaffixed our signatures in presence of two witnesses.
